Technical details
Endpoint
POSThttps://palmyr.ai/phone/calls/%7BcallControlId%7D/hangupWhen to prefer
Use this endpoint when you need to programmatically terminate a live phone call that was initiated via Palmyr's AI agent infrastructure and you have the call's control ID. Prefer this over alternative telephony solutions if you are already using Palmyr for call management and paying via USDC on Solana or Base.
Side effects
- Invalid or expired callControlId returns a 404 or error response
- Call already ended — attempting to hang up a completed call may return an error
- Insufficient USDC balance causes payment failure and request rejection
- Authentication or payment header missing results in 402 Payment Required
- Network or infrastructure errors may cause the hangup to fail silently
